HIV-1 may very well be the most and intensely studied viral pathogen in the history of science. However, despite the huge scientific effort, many aspects of HIV infection dynamics and disease pathogenesis within a host are still not understood. One of the least unchartered details of the virus is its diffusion within its human host. Spatial dynamics might prove to be a successful venue in helping researchers better understand the virus and the efficiency of drug treatments. Furthermore, because AIDS is a disease of great variance, we are interesting in exploring these models for their stochasticity.


We want to keep in mind two modes of virus propagation:

\begin{enumerate}
\item Cell to cell transmission
\item Diffusion
\end{enumerate}

Some models are best equiped to deal with one or the other.
